Running AI agents on WhatsApp: why the platform forces human-in-the-loop design

A developer building customer-facing agents on WhatsApp Business API (n8n + LLM + CRM) shares hard-won lessons: WhatsApp's per-number quality rating means bad agent messages can get the whole channel restricted, so the blast radius of a hallucination is far bigger than on web chat. The 24-hour reply window forces agents to detect the conversation's 'time zone' and fall back to pre-approved templates. His rule: autonomous replies only for low-stakes intents; pricing, complaints and refunds get human one-tap approval on LLM-drafted replies. The approval queue also turned out to be a selling point for small-business owners who distrust full autonomy.
